Wheel hubs for a motor-vehicle wheel hub assemblies provided with a bearing unit in turn which include at least one row of rolling bodies, the wheel hub being provided with at least two sheet-metal elements which are rigidly joined together, wherein a first sheet-metal element forms a raceway for the at least one row of rolling bodies.

A manufacturing method of a wheel bearing device, the wheel bearing device including an outer ring member, an inner shaft member that includes a shaft portion that has an inside raceway and a flange portion, a plurality of rolling elements, a seal provided at an end portion of the outer ring member on the first axial side and including an axial lip, and a lip contact surface provided on the side of the inner shaft member and contacted by the axial lip, includes: processing the outside raceway with a distance in an axial direction from a first reference position being managed, a first reference position being set on the outer ring member; and providing the seal at a predetermined position, in the axial direction, of the outer ring member with respect to the first reference position.

Disclosed are an in-wheel working device and an automobile including the in-wheel working device. According to one aspect of the present disclosure, provided is an in-wheel working device including a rotation detection sensor coupled to a wheel bearing. The rotation detection sensor includes: a sensor stator coupled to an outer race of the wheel bearing; and a sensor rotor coupled to a hub of the wheel bearing. The sensor stator includes a printed circuit board (PCB) substrate having a surface on which a coil pattern made of a metal material is formed.

A bearing unit for a wheel hub assembly for motor vehicles, having a first raceway which is a radially outer and axially outer raceway and a second raceway which is a radially outer and axially inner raceway, a third raceway which is a radially inner and axially outer raceway and a fourth raceway which is a radially inner and axially inner raceway; an axially outer row and an axially inner row of rolling bodied, interposed, respectively, between the first raceway and the third raceway and between the second raceway and the fourth raceway; at least one raceway is provided with a first raceway portion and a second raceway portion, the raceway portions being tangential to the rolling body of the row of rolling bodies at two different contact angles the first contact angle of the first raceway being smaller than the second contact angle of the second raceway portion.

A hub-bearing unit with an axis of rotation includes a stationary, radially external ring, a radially internal flanged hub, rotatable about the axis and including a first shoulder, a second shoulder, a first relief groove, and a section (SR) radially opposite the first relief groove. At least one row of rolling bodies is interposed between the external ring and the flanged hub. The hub-bearing unit includes a first radial ball bearing and a second radial ball bearing interposed between a stem of a constant velocity joint and the flanged hub and opposite the first shoulder and the second shoulder. The second ball bearing mounts inside a seat of the flanged hub and a spacer axially abuts the second shoulder and mounts inside the seat between the second shoulder and the second ball bearing. The seat includes a second relief groove formed in an axially external position relative to section (SR).

A hub assembly includes an inner rotatable hub having inboard and outboard axial ends, a radial flange extending outwardly from the outboard axial end and connectable with the wheel, an inner circumferential surface, and an opposing outer circumferential surface providing inboard and outboard inner races. An outer hub is disposed about the inner hub, connectable with the chassis and has inboard and outboard axial ends, an outer circumferential surface and an inner circumferential surface. The inner surface provides inboard and outboard outer races and a central surface section extending between the two outer races. First and second sets of rolling elements are disposed between the inner and outer races. One or more sensors are each disposed on the central surface section of the outer hub and are each configured to sense strain within the outer hub generated by the rolling elements.

A packaging system having an outboard guard and an outboard retainer cap. The outboard guard includes an outboard guard opening having a hole through the planform of the outboard guard, an engagement portion having an annular surface radially surrounding the outboard guard opening, an outboard bearing protector portion having an annular surface radially surrounding the engagement portion of the outboard guard, and an outer rim having an annular surface radially surrounding the outboard bearing protector portion. The outboard retainer cap is configured to be removably affixed to the outboard guard and includes an outboard alignment protrusion having a circular surface, an engagement portion having an annular surface radially surrounding the outboard alignment protrusion, and a retaining flange having an annular surface radially surrounding the engagement portion of the outboard retainer cap.
